As shown in these drawings, the satellite radio-controlled wristwatch 1 includes a windshield 31, a bezel 32 that holds the windshield 31, a cylindrical trunk 38, and a back cover 39 provided under the trunk 38. . These constitute the outer shape of the satellite radio-controlled wristwatch 1. The windshield 31 includes a transparent material such as sapphire glass. The body 38 and the bezel 32 are sandwiched between the windshield 31 and the back cover 39. Hereinafter, the direction from the center of the satellite radio-controlled wristwatch 1 toward the windshield 31 is referred to as “up” and the direction toward the back cover 39 is referred to as “down”. In a state where the windshield 31 is assembled to the satellite radio-controlled wristwatch 1, the surface constituting the outer side is referred to as the front side surface, and the surface constituting the inner side is referred to as the back side surface.

  The body 38 is made of metal and has a hole penetrating from top to bottom. The bezel 32 is a ring-shaped member corresponding to the shape of the upper end of the hole of the barrel 38, and the bezel 32 is connected to the barrel 38 by being fitted into the upper end of the hole. Here, the bezel 32 may be made of metal, may be made of a high dielectric material (for example, ceramics), or may be a combination of metal and high dielectric material. The back cover 39 is made of metal and has a flat surface corresponding to the shape of the lower end of the hole of the body 38, and the back cover 39 is fitted into the lower end of the hole of the body 38. The windshield 31 has a planar shape corresponding to the shape of the upper end of the opening of the bezel 32 and is fitted into the upper end of the opening of the bezel 32. The windshield 31 and the bezel 32 are in contact with each other via a non-conductive packing 33, and the windshield 31 is fixed by the non-conductive packing 33. Further, the bezel 32 and the body 38 are in contact with each other via a non-conductive packing 37, and the bezel 32 is fixed to the body 38 by the packing 37. Further, the crown 36 is assembled so as to protrude from a predetermined position in the trunk 38.

  FIG. 3 is a diagram illustrating a three-dimensional arrangement of the windshield glass 31, the index 71, the blindfold layer 61, and the antennas 10a and 10b according to FIG. FIG. 3 is a view for showing the order of the windshield glass 31, the index 71, the blindfold layer 61, and the antennas 10a and 10b in the vertical direction. In FIG. 3, the layers of the windshield 31, the index 71, the blindfold layer 61, and the antennas 10 a and 10 b are described so as to be separated from each other in the vertical direction, but actually the adjacent layers are in contact with each other. Even if the layers are not adjacent to each other, they are in contact with each other if there are no other layers in between.

  An index 71 is printed on the periphery of the windshield glass 31 shown in FIGS. In the example of FIG. 1, the index 71 is a time character. An annular blind layer 61 is also printed on the rear surface of the windshield 31 along the periphery of the windshield 31. The blindfold layer 61 is located below the index 71, and the index 71 is disposed between the blindfold layer 61 and the windshield 31. The blind layer 61 is made of a non-conductive material and does not affect the antenna characteristics when in contact with the antennas 10a and 10b. Even if a metal vapor deposition layer for an index is provided on the windshield glass side of the blindfold layer 61, the surfaces in contact with the antennas 10a and 10b are made of a non-conductive material. The antenna characteristics of 10b are not affected.

  The blindfold layer 61 is provided with a notch 75 as a mark. The positions of the notches 75 are provided at the 12 o'clock and 6 o'clock positions in the example of FIG. Further, an upper mark 76 is disposed at a position on the upper surface of the bezel 32 and adjacent to the notch 75. The notch 75 and the upper mark 76 are used when the windshield 31 is fitted into the bezel 32, and details will be described later.

  The satellite radio-controlled wristwatch 1 includes antennas 10a and 10b, two conductive pins 41, a ring-shaped dial ring 34, a dial 51, an hour hand 52a, a minute hand 52b and a second hand 52c, a solar cell 53, a ground plane 54, and a wiring board 43. Circuit board 47 and motor. These are arranged in a space surrounded by the windshield 31, the bezel 32, the trunk 38, and the back cover 39.

  FIG. 4 is a plan view of the windshield 31 according to FIG. 1 as seen from the back side. The antennas 10a and 10b are disposed on the lower surface of the blindfold layer 61, and are disposed so as to overlap the blindfold layer 61 and extend along the periphery of the windshield 31 in plan view. Note that the notch 75 of the blind layer 61 and the antennas 10a and 10b do not overlap in plan view. By arranging the antennas 10 a and 10 b on the back side of the blindfold layer 61, the antennas 10 a and 10 b can be prevented from being viewed from the front side of the windshield 31.

  In the example of FIG. 4, each of the antennas 10 a and 10 b has an arc shape and is attached to the rear surface of the windshield 31. In practice, the antennas 10a and 10b and the windshield 31 function as antennas by attaching the antennas 10a and 10b to the windshield 31 that is a dielectric. Hereinafter, for convenience of explanation, “antenna” refers to 10a and 10b. The antennas 10a and 10b receive satellite signals transmitted from the satellites. In the present embodiment, the antennas 10a and 10b are so-called dipole antennas, and receive radio waves having a frequency of about 1.6 GHz transmitted from a GPS (Global Positioning System) satellite. GPS is a kind of satellite positioning system, and is realized by a plurality of GPS satellites orbiting around the earth. The antennas 10a and 10b are not circular rings, and are not rotating bodies about the axis of the windshield 31 in the rotation direction.

  One end of each of the antennas 10 a and 10 b is in contact with the conductive pin 41. The conductive pin 41 is a so-called probe pin and is a kind of connector that receives signals from the antennas 10a and 10b and transmits the signals to the receiving circuit. The number of conductive pins 41 is the same as the number of antennas 10a and 10b. The conductive pins 41 are electrically connected to the corresponding antennas 10a and 10b from the back side thereof. Radio wave analog signals received by the antennas 10 a and 10 b are input to the receiving circuit via the conductive pins 41. Both ends of the conductive pin 41 are expanded and contracted by a spring, and the upper end of the conductive pin 41 is in contact with one end of the antennas 10a and 10b. The lower end of the conductive pin 41 is in contact with a connection terminal provided on the wiring board 43. The position of the conductive pin 41 in a plan view is fixed by the turn ring 34 and the ground plane 54. The conductive pin 41 extends in a direction away from the windshield 31 when viewed from the antennas 10a and 10b.

  The receiving circuit includes a high frequency circuit (RF circuit) and a decoding circuit. The high frequency circuit operates at a high frequency, amplifies and detects analog signals received by the antennas 10a and 10b, and converts them into baseband signals. The decoding circuit decodes the baseband signal output from the high-frequency circuit and generates a bit string indicating the content of data received from the GPS satellite. The hour hand 52a, the minute hand 52b, and the second hand 52c are rotated by a drive mechanism including a motor and a train wheel, and display the current time. The drive mechanism is controlled based on time information and a clock signal included in the generated bit string. Instead of the conductive pin 41, a connector that is adjacent to the antennas 10a and 10b while being separated may be disposed under the antennas 10a and 10b. The connector is supplied with power from the receiving circuit, and the arc-shaped electromagnetic coupling portion is electromagnetically connected to the antennas 10a and 10b, thereby transmitting signals received by the antennas 10a and 10b to the receiving circuit.

  In the satellite radio-controlled wristwatch 1 shown in FIGS. 1 to 3, the antennas 10a and 10b and the conductive pins 41 (connectors) must be brought into contact with each other at appropriate positions. On the other hand, when the windshield 31 is viewed from the front side, the positions of the antennas 10a and 10b cannot be visually recognized by the blindfold layer 61, and it is difficult to align them using the antennas 10a and 10b themselves. Hereinafter, a method of aligning the positions of the windshield glass 31 on which the antennas 10a and 10b are arranged and the conductive pins 41 when the satellite radio wave wristwatch 1 is manufactured will be described.

  5A and 5B are plan views for explaining an example of the manufacturing process of the satellite radio-controlled wristwatch 1. First, the windshield 31 is fixed to a jig, and the index 71 is printed on the back surface of the windshield 31 (see FIG. 5A). This jig has a fixed position of the windshield 31 and a portion fixed to the printing apparatus. Thereby, the position of the windshield 31 fixed to the jig at the time of printing can be specified.

  Next, the blind layer 61 is printed on the surface on the back side of the windshield 31 on which the index 71 is printed (see FIG. 5B). Here, the blindfold layer 61 is provided with a notch 75, and the notch 75 shown in FIG. 5B is visually recognized from both the front side and the back side of the windshield 31. The notch 75 serves as a mark indicating a rotational position when the windshield 31 is assembled to the bezel 32 or the like. In addition, the blindfold layer 61 may be provided by surface processing which raises a reflectance instead of printing. Moreover, after printing the blindfold layer 61, you may remove the windshield 31 from a jig | tool.

  Next, the antennas 10a and 10b are affixed to the back side of the blindfold layer 61 in the windshield 31 while using the notch 75 as an alignment mark. The windshield 31 shown in FIG. 4 is the same as that in the state where this process is completed. Since the blindfold layer 61 is provided along the outer edge of the windshield 31 in plan view, the antennas 10 a and 10 b are also provided along the periphery of the windshield 31. In addition, the notch 75 and the antennas 10a and 10b are arranged so as to have a predetermined positional relationship by positioning using the notch 75. Here, the predetermined positional relationship means that the difference between the angle of the notch 75 and the angles of the antennas 10a and 10b viewed from the center of the windshield 31 falls within a predetermined range.

  And the windshield 31 is assembled | attached to the bezel 32, using the notch 75 as a mark of alignment. At this time, for example, the windshield glass 31 is assembled to the bezel 32 so that the upper mark 76 provided on the bezel 32 and the notch 75 of the blindfold layer 61 are aligned. Thereby, the windshield 31 is assembled | attached with the bezel 32 so that it may become a predetermined positional relationship. Here, the bezel 32 is assembled in advance to the body 38, and the upper mark 76 of the bezel 32 and the conductive pin 41 have a predetermined positional relationship. Then, by aligning the notch 75 of the windshield 31 as a mark, the positions of the antennas 10a and 10b having a predetermined positional relationship with the notch 75 and the conductive pins 41 having the predetermined positional relationship with the bezel 32 are determined. It becomes possible to match. Thereby, even if it has the blindfold layer 61, it becomes possible to contact the antennas 10a and 10b and the conductive pin 41 appropriately. The index 71 and the notch 75 overlap in plan view so that the notch 75 is not conspicuous.

  Note that the body 38 may be integrated with the bezel 32. In this case, in the above process, the antennas 10a and 10b and the conductive pins 41 are appropriately brought into contact with each other by assembling the windshield glass 31 in the opening on the upper side of the trunk 38 while using the notch 75 as an alignment mark. .

  In the example described so far, the number of the notches 75 as the mark is two, but may be one. In addition, when a plurality of marks visually recognized from the front side of the windshield glass 31 are provided, in order to clarify which rotational position each mark corresponds to, the shape of each mark may be different from each other. Good. For example, the shape of the notch 75 may be V-shaped, U-shaped, or the like. In this case, even if there is no index 71, there is no possibility that the rotational position corresponding to the mark is wrong.

  Instead of the upper mark 76 provided on the bezel 32, a member fixed to the barrel 38 may be used as the mark. For example, the windshield 31 may be assembled to the bezel 32 using the description of the crown 36 or the dial 51 as a mark.

  Here, instead of the cutout 75, an opening 72 that is a through hole provided in the blindfold layer 61 may be provided as a mark. FIG. 6 is a plan view showing another example of the windshield 31. FIG. 6 is a plan view when viewed from the front side of the windshield 31. Moreover, FIG. 7 is sectional drawing in the VII-VII cut line of the windshield 31 shown in FIG.

  As shown in FIG. 6, for example, numerical apertures 72 are provided at positions at 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock in the blindfold layer 61, and the windshield 31 is provided. From the front side, it is also visible as a time character instead of the index 71. A filter 66 is provided below the opening 72 in the blind layer 61 so as to cover the opening 72, and antennas 10 a and 10 b are attached to the lower side of the filter 66. Part of the antennas 10 a and 10 b is in contact with the blindfold layer 61. Here, the filter 66 may not be provided. In the absence of the filter 66, the color (metal reflection) of the antennas 10a and 10b below the opening 72 can be seen. In the case where the filter 66 is provided, it is possible to freely design the color and the appearance viewed from the front side of the windshield 31.

  The manufacturing process of the satellite radio-controlled wristwatch 1 according to the example of FIGS. 6 and 7 is different from the manufacturing process described with reference to FIGS. 5A and 5B, there is no step of printing the index 71, and the step of printing the blindfold layer 61. There is a step of printing the filter 66 between the steps of attaching the antennas 10a and 10b. The opening 72 is used as an alignment mark in the process of attaching the antennas 10a and 10b with light transmitted through the filter 66. The opening 72 is used as an alignment mark in the process of assembling the windshield 31 to the bezel 32 or the trunk 38.

  FIG. 8 is a diagram illustrating another example of the arrangement of the windshield glass 31, the index 71, the blindfold layer 61, and the antennas 10a and 10b. FIG. 8 is a diagram corresponding to FIG. 3 and shows the order of the windshield glass 31, the index 71, the blindfold layer 61, and the antennas 10a and 10b in the vertical direction. In the example of FIG. 8, unlike the examples of FIGS. 6 and 7, the index 71 is arranged on the opening 73 that is a through hole provided in the blindfold layer 61 so as to cover the opening 73. The lower color of the index 71 is different from that of the blindfold layer 61.

  The manufacturing process of the satellite radio-controlled wristwatch 1 according to the example of FIG. 8 is different from the manufacturing process described with reference to FIGS. 5A and 5B in the following points. The first difference is that in the step of attaching the antennas 10a and 10b, the hole-shaped opening 73 is used as a mark for alignment. Note that the position of the opening 73 can be easily visually recognized from the back side of the windshield 31 due to the difference in color between the blindfold layer 61 and the index 71. The second difference is that the index 71 is used as an alignment mark in the process of assembling the windshield glass 31 to the bezel 32 or the body 38. The index 71 may include a minute mark having a color different from that of other portions of the index 71 for accurate alignment. In the example of FIG. 8, the mark that is visible from the back and used for attaching the antennas 10 a and 10 b is different from the mark that is visible from the front side and used for assembling the windshield 31. However, when the index 71 and the blindfold layer 61 are printed, the windshield 31 is fixed to a jig that can specify the fixing position of the windshield 31. Misalignment is sufficiently suppressed. Thereby, even if the mark used by a process differs, it becomes possible to make antenna 10a, 10b and the conductive pin 41 contact appropriately.

  FIG. 9 is a diagram illustrating another example of the arrangement of the windshield glass 31, the index 71, the blindfold layer 61, and the antennas 10a and 10b. FIG. 10 is a plan view of the windshield 31 according to FIG. 9 as viewed from below. In FIG. 9, unlike the example of FIG. 8, a notch 75 is provided instead of the opening 73, and an index 71 is disposed on the notch 75 so as to cover the notch 75. In the example of FIG. 9, the size of the notch 75 is smaller than the index 71, and the notch 75 is hidden by the index 71 when viewed from the surface. Further, the lower color of the index 71 is different from that of the blindfold layer 61. The manufacturing process of the satellite radio-controlled wristwatch 1 according to the example of FIG. 8 is the same as that of the example of FIG. 8 except that a cutout 75 is used instead of the opening 73 in the process of attaching the antennas 10a and 10b. In the example of FIG. 9, the mark such as the notch 75 can be made inconspicuous when viewed from the front side.

  Here, an opening 74 may be provided in a part of the character indicated by the index 71. FIG. 11 is a diagram illustrating another example of the index 71. The opening 74 in the character area of the index 71 is used as an alignment mark in the process of assembling the windshield 31 to the bezel or the trunk 38. Further, by combining with the notch 75, the opening 74 is also visually recognized from the back side of the windshield 31. Accordingly, the opening 74 is used as a mark in the process of attaching the antennas 10a and 10b. Further, instead of the opening 74, a part of the index 71 may be visually recognized from both sides, and a dot having a different color from the other area may be printed as a mark. Instead of the opening 74, dots are used for alignment in the process of attaching the antennas 10a and 10b and the process of assembling the windshield 31 to the bezel 32 or the like.

  Further, an antenna mark for positioning the antennas 10 a and 10 b may be disposed below the blindfold layer 61. FIG. 12 is a plan view showing another example of the windshield 31. FIG. 12 is a plan view showing the windshield 31 viewed from the back side. FIG. 13 is a cross-sectional view taken along the line XIII-XIII of the windshield 31 shown in FIG. 12 and 13, an index 71 (not shown) is provided on the rear surface of the windshield 31, and the index 71 is a mark that can be seen from the front side. On the other hand, below the blindfold layer 61, a guide region 79 having a shape surrounding the antennas 10a and 10b in a plan view is printed. This guide region 79 serves as an antenna mark. In addition, the guide area | region 79 does not need to be circular arc shape. For example, the guide region 79 may be provided only around the ends of the antennas 10a and 10b. The antennas 10 a and 10 b are attached to the lower side of the guide region 79. The blindfold layer 61 has an annular shape that does not have a notch 75 or a hole.

  14A and 14B are plan views for explaining another example of the manufacturing process of the satellite radio-controlled wristwatch 1. As in the example of FIGS. 5A and 5B, first, the windshield glass 31 is fixed to a jig capable of specifying the position where the windshield glass 31 is fixed, and the index 71 is printed on the back surface of the windshield glass 31 (see FIG. 5A). ). Next, the blindfold layer 61 is printed on the back surface of the windshield 31 on which the index 71 is printed (see FIG. 14A).

  Next, a guide region 79 is printed on the blindfold layer 61 in a state where the windshield 31 is fixed to the jig (see FIG. 14B). The guide region 79 is a mark indicating a position where the antennas 10a and 10b are attached in the next step. All of the steps of printing the index 71, the blind layer 61, and the guide region 79 are fixed to the same jig. Thereby, the index 71, the blindfold layer 61, and the guide region 79 have a certain positional relationship. When the guide area 79 is printed, the windshield 31 is removed from the jig.

  Next, the antennas 10 a and 10 b are pasted on the guide region 79 while using the guide region 79 as a mark for alignment. The windshield 31 shown in FIG. 12 is the same as that in the state where this step is finished. In this step, the antennas 10a and 10b and the guide region 79 are arranged so as to have a certain positional relationship with each other.

  And the windshield 31 is assembled | attached to the bezel 32, utilizing the index 71 as a mark of alignment. Thereby, the windshield 31 is assembled | attached with the bezel 32 so that it may become a predetermined positional relationship. Thereby, even if it has the blindfold layer 61, it becomes possible to contact the antennas 10a and 10b and the conductive pin 41 appropriately.

  In the step of arranging the antennas 10a and 10b on the blindfold layer 61, the positioning may be performed by using a jig for fixing the windshield 31 when the blindfold layer 61 is printed instead of the antenna mark. .

By using the mark of the jig for positioning, the antennas 10a and 10b and the mark visible from the front side have a predetermined positional relationship.

[Second Embodiment]
The present invention can also be applied to the case where the windshield 31 is assembled to the bezel 32 before the bezel 32 is assembled to the body 38. Hereinafter, the second embodiment in this case will be mainly described with a focus on differences from the other embodiments.

  FIG. 15 is a plan view showing an example of the appearance of the satellite radio-controlled wristwatch 1 according to the second embodiment of the present invention, and FIG. 16 is a plan view of the bezel 32 and the windshield 31 included in FIG. It is. FIG. 17 is a cross-sectional view taken along line XVII-XVII of the satellite radio-controlled wristwatch 1 shown in FIG.

  In the satellite radio-controlled wristwatch 1 according to the second embodiment, the blindfold layer 61 provided on the back side of the windshield 31 has an annular shape, and is not provided with an index 71 or a hole serving as a mark indicating the rotational position. In addition, an upper mark 76 is attached to a region indicating a specific rotational position (for example, the direction of 12 o'clock) on the front side surface of the bezel 32, and a specific rotational position (for example, the outer surface of the body 38, for example). An exterior mark 78 is provided in a region indicating the same direction as the upper mark 76. In addition, a lower mark 77 is attached to a portion having a predetermined positional relationship with the upper mark 76 on the back side of the bezel 32 (the surface that cannot be seen from the outside) and outside the opening in which the windshield 31 is assembled. ing. The upper mark 76 and the lower mark 77 indicate the rotational position of the bezel 32, and the exterior mark 78 indicates the rotational position of the barrel 38.

  Further, a movement 82 including a dial 51 and the like is fixed inside the body 38, and the conductive pin 41 extends upward from the movement 82. The antennas 10 a and 10 b attached to the lower side of the blindfold layer 61 are in contact with the conductive pins 41.

  Next, the manufacturing process of the satellite radio-controlled wristwatch 1 shown in FIGS. 15 to 17 will be described. 18A to 18D are diagrams for explaining an example of the manufacturing process of the satellite radio-controlled wristwatch 1. First, an upper mark 76 and an index 81 are printed on the front side of the bezel 32 (see FIG. 18A), and a lower mark 77 is added on the back side of the bezel 32. In this step, for example, if the bezel 32 is fixed to a jig in advance, the upper mark 76 and the lower mark 77 can be arranged so as to have a predetermined positional relationship with each other.

  Next, the windshield 31 is assembled to the bezel 32 (see FIG. 18B). In this step, it is not necessary to adjust the rotational position of the windshield 31. Then, a blindfold layer 61 is printed on the back surface of the windshield 31 assembled to the bezel 32, and the antennas 10a and 10b are pasted so as to overlap the blindfold layer 61 while using the lower landmark 77 as a landmark (FIG. 18C). reference). Through these steps, a bezel assembly including the bezel 32 and the windshield 31 with the antennas 10a and 10b is formed (see FIG. 18D).

  In the next step, the bezel 32 is assembled to the barrel 38. In this step, the upper mark 76 attached to the bezel 32 and the exterior mark 78 attached to the trunk 38 are used as alignment marks. Since the windshield 31 and the bezel 32 have a predetermined positional relationship, the upper mark 76 also indicates the rotational position of the windshield 31. Thereby, the bezel assembly including the windshield 31 and the bezel 32 and the body 38 have a predetermined positional relationship. In the step of assembling the bezel 32 to the body 38, the index 81 may be used as an alignment mark instead of the upper mark 76, or a member (such as the crown 36) fixed to the cylinder 38 is positioned instead of the exterior mark 78. It may be used as a mark for alignment.

  Even in the manufacturing method described here, the antennas 10a and 10b can be assembled so that the positions of the antennas 10a and 10b and the position of the trunk 38 have a predetermined positional relationship. And it becomes possible to make the conductive pin 41 contact appropriately.

  Here, before assembling the windshield glass 31 to the bezel 32, the blind glass layer 61 may be attached to the windshield glass 31 and the antennas 10 a and 10 b may be disposed on the blind mask layer 61. 19A and 19B are diagrams for explaining another example of the manufacturing process of the satellite radio-controlled wristwatch 1.

  In this manufacturing process, first, the blindfold layer 61 is printed on the rear surface of the windshield glass 31 and the non-circular antennas 10a and 10b are attached along the peripheral edge of the windshield glass 31 and overlapping the blindfold layer 61 ( (See FIG. 19A). In the process of printing the blindfold layer 61 and attaching the antennas 10a and 10b, it is not necessary to adjust the rotational position of the windshield 31. However, also in these steps, the distance from the outer peripheral edge of the windshield glass 31 of the blindfold layer 61 and the antennas 10a and 10b and the positional relationship in the rotation direction between the antenna 10a and the antenna 10b are adjusted.

  In parallel with the above process, the upper mark 76 and the lower mark 77 are attached to the bezel 32 so that the upper mark 76 and the lower mark 77 have a predetermined positional relationship with each other. The upper mark 76 indicates the rotational position of the bezel 32, and the lower mark 77 has a predetermined positional relationship with the upper mark 76. This process is similar to that described for FIG. 18A.

  And the windshield 31 is assembled | attached to the bezel 32 (refer FIG. 19B). In this step, the positions of the antennas 10a and 10b and the lower mark 77 provided on the bezel 32 are used as alignment marks. Thereby, the antennas 10a and 10b and the lower mark 77 have a predetermined positional relationship. By these steps, a bezel assembly including the bezel 32 and the windshield 31 with the antennas 10a and 10b is formed. The shape of this bezel assembly is similar to that shown in FIG. 18D. Next, the bezel 32 is assembled to the cylinder 38 while using the upper mark 76 attached to the bezel 32 and the exterior mark 78 attached to the cylinder 38 as alignment marks. Thereby, the bezel 32 is assembled so as to have a predetermined positional relationship with the body 38.

  Even with such a manufacturing method, the antennas 10a and 10b and the conductive pin 41 can be appropriately brought into contact with each other.
